The transceiver GPIO pins default to inputs at reset. There are no programmable pullups on these pins. Unused GPIO pins
should be tied to ground if left as inputs, or if left unconnected, they should be programmed as outputs set to the low state.
During low power modes, input must remain driven by MCU.
By default MISO is tri-stated when CE is negated. For low power operation, miso_hiz_en (Bit 11, Register 07) should be set
to zero so that MISO is driven low when CE is negated.
